Title: Special issue of Computers and Fluids in honor of Cecil E. (Chuck) Leith

Abstract

Here, this special issue of Computers and Fluids is dedicated to Cecil E. (Chuck) Leith in honor of his research contributions, leadership in the areas of statistical fluid mechanics, computational fluid dynamics, and climate theory. Leith's contribution to these fields emerged from his interest in solving complex fluid flow problems--even those at high Mach numbers--in an era well before large scale supercomputing became the dominant mode of inquiry into these fields. Yet the issues raised and solved by his research effort are still of vital interest today.

This special issue of Topics in Catalysis honors Professor S. Ted Oyama for his Awards in Petroleum Chemistry and Fuel Science Research. These awards were celebrated at two American Chemical Society (ACS) symposia in 2014. First, the ACS’s Distinguished Research Award in Petroleum Chemistry Symposium, took place at the 247th ACS National Meeting in Dallas, TX, during March 17-19, 2014 and the second one, the ACS’s Storch Award in Fuel Science Symposium, took place at the 248th ACS National Meeting in San Francisco, CA, during August 10-12, 2014. Professor Oyama received the 2014 ACS Distinguished Research Award in Petroleum Chemistrymore » ‘‘for his substantial contributions to the field of heterogeneous catalysis’’ including the discovery of highly active transition metal phosphide catalysts for hydrotreatment of petroleum and coal-derived feedstocks and biomass refining, the development of new compositions, and the understanding of their reaction mechanisms by in situ spectroscopic techniques at high temperatures and pressures of reaction. In light of this recognition, Professor Oyama was also awarded the 2014 ACS Storch Award in Fuel Science ‘‘for his broad contributions to the field of fuel science’’ including the production of hydrogen by catalytic reforming, selective oxidation of hydrocarbons, biomass conversion, their reaction kinetics and mechanisms, and spectrokinetic methods to study catalysts in situ at reaction conditions and theory and application of inorganic membranes for separation of hydrogen and fuel-relevant gases. Finally, this special issue consists of contributions by catalysis researchers who participated in the two ACS symposia honoring Professor Oyama’s Awards.« less

The US DOE recently initiated an effort to develop accident tolerant fuel designs for potential use in commercial power reactors. Evaluation of various fuel design concepts will require a broad array of testing that will include performance attributes at both steady state and transient irradiation conditions. The first stage of the transient testing program is intended to establish the relative performance limits of each proposed concept and to support development of first-draft fuel performance models. It is anticipated that this data can subsequently be used as the basis for larger scale qualification testing. This initial stage of the testing programmore » is outlined in this paper.« less

The performance of pipelined processors is limited by data dependencies and brach instructions. In order to achieve high performance, mechanisms must exist to alleviate the effects of data dependencies and branch instructions. Furthermore, in many cases, for example the support of virtual memory, it is essential interrupts be precise. In multiple functional unit pipelines processors where the instructions can complete and update the state of the machine out of program order, hardware support must be provided to implement precise interrupts. In this paper, the authors combine the problems of data dependency resolution and precise interrupt implementation. They present a designmore » for a hardware mechanism that resolves dependencies dynamically and, at the same time, guarantees precise interrupts. Simulation studies show that, by resolving dependencies, the proposed mechanism is able to obtain a significant speedup over a simple instruction issue mechanism as well as implement precise interrupts.« less
